screw hole in copper pipe

I was putting a plywood sub floor down today in my entrance way on top of plank flooring and screwing the plywood down. When I was finish I proudly looked at my work. Thinking I was getting closer to laying down my tiles. Then I looked at my raditors and was hoping I was not all that dumb, unforunatly I was, removed the questionable screw was greeted by a shower.

I have now drained the heating system(thank goodness it is summer) and have removed the new plywood and have a small hole in the inch coffer pipe. Is their some sort of patch I can put over the hole or would I have to have the pipe cut out and new piece put in its place. If I have to remove the pipe I will have to pull up some of the plank subfloor.

To do that properly, cut it OFF CENTER, so you create a piece with a slight "C" appearance. That will "snap" onto the pipe and create the pressure necessary to make the tight fit a proper solder joint requires.
